Sordin Isle is a small island off the coast of the Lurkertail in the Nightspell Moors, and is considered part of the Tevari Isles. The island is largely uninhabited save for a small settlement on the southern coast that operates a small mine as well as logging operations on the island's dense forest. The depths of the island features an intricate cave system that connects to the mainland of the Moors, and is often used as a hideout for bandits due to the lack of supervision in the area.
The lich Ventrex Caustar once used the island as a headquarters for his bandit operations, and hid his phylactery deep within its ancient caves.
